LBRICATOR FOR CAR JOURNALS Filed April 19. 1929 2 sheets-sheet -2 In v'entor T/lfzilz'awl Patented June 24, 1930 UNITED STATES WILLIAM I.. KNIGHT, OF GREENSBURG, INDIANA LUBRIGATOR FOR GARl TOURNAI-S` Application filled April 19,

The present invention appertains to new and useful improvements in lubrication and more particularly to a novel lubricator for car journals.

The principal object of the invention is to provide a lubricator for constantly lubricating the journal portion of car axles.

Another important object of the invention is to provide a lubricator for car journals wherein means is provided for constantly maintaining the axle lubricated regardless of the amount of lubricant available.

Another important object of the invention is to provide a lubricator for the journal ends of car axles wherein means is provided for tensionally maintaining the lubricator constantly in contact with the axle.

These and other important objects of the invention will become more apparent to the reader after considering the invention as described and claimed hereinafter.

In the drawings Figure 1 represents a vertical sectional view through a conventional car axle journal and the present invention attached thereto.

Fig. 2 represents a vertical sectional view through the improved lubricator in association with the journal end of a car axle.

Fig. 3 represents a top plan view of the lubricator showing the movable web partly broken away to disclose the position of the rolls.

Fig. 4. represents a perspective view of one of the rolls.

Fig. 5 represents a fragmentary vertical transverse sectional view of the device.

Fig. 6 represents a vertical sectional detail view of the lubricator.

Referring to the drawings wherein like numerals designate like parts, it will be seen that the lubricator is attachable to a conventional car journal structure such as is clearly shown in Fig. 1 of the drawings.

This particular type of journal consists of a housing A and mount B for the brass C, which is grooved to receive the journal portion D of the car angle E.

The invention is generally referred to by the numeral 5 and includes a reservoir 6 preferably of rectangular shape in plan. The

1929. Serial No. 356,422.

longitudinal side Walls of the reservoir are flaredv outwardly at their lower portion 7 while Athe bottom 8 is curved transversely in the manner clearly shown in Fig. 1.

The side walls have outwardlyV diverged flanges 9 which project above the top of the receptacle and each of which is provided with an inwardly disposed longitudinal rib 10. A gasket 11, preferably of steelvwool or some similar material, is interposed between the flanges 9 and the portion D `of the axle in the manner shown in Fig. l.

A pair of upper rolls 12-12 are rotatably mounted on the pin 13 extending longitudinally through the reservoir. A third roll 12 is rotatably mounted on a pin 13 in parallelism to theother rolls and in close proximity to the bottom of the reservo-ii'. A web 14 is trained over the roll in the manner shown in F ig. 1, the lower roll serving to feed the web close to the bottom of the reservoir, so that even though a small amount of loil be in the reserlvoir, the web will nevertheless be lubricatec.

Ears 14 at the ends of the flanges 9 are attached each to one end of a coiled spring 15 which has its opposite end anchored to one side wall of the journal housing A at a point well above the lubricating device, and substantially as shown in Fig. 1.

It will thus be seen that the present invention embodies many novel details and furthermore, the constructing of this device from sheet metal by any of the well known forming operations will render this article a cheap item in railway rolling stock maintenance in comparison to its utility.

Y It is to be understood that numerous changes in the specific shape, size, and materials may be resorted to without departing 90 from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as newis 1. A lubricator for car axles comprising a reservoir for containing a lubricant, and tensional means for urging the reservoir against the axle, and packing means interposed between the reservoir and the car axle.

2. A lubricator for car axles comprising a reservoir for containing a lubricant, tensional means for pulling the reservoir against the axle, feed means Within the reservoir for delivering lubricant from the. reservoir to the 5 axle, said means consisting of spaced rolls journaled in said reservoir and a Web disposed over said longitudinally extending parallel rolls.

3. A lubricator `for car axles comprising m a reservoir for containing a lubricant, tensional means for pulling the reservoir against the axle, feed means Within the reservoir for delivering lubricant from the reservoir to the axle, said means consisting of a. pair of upper rolls Within the reservoir and a lower roll adjacent the bottom of the reservoir, and a web trained over said rolls.

4i. A lubricator for car axles comprising a reservoir, said reservoir having a constricted open top, outwardly dii/erging ianges at the upper edges of the reservoir, and a packing .gasket interposed between the flanges and the. car axle. Y

5. A iubricator for .car axles comprising l, a reservoir, said reservoir having a constructed open top, outwardly diverging ianges at the upper edges oi tlie reservoir, a packing gasket interposed between the flanges and the car axle, and tensional means for normal- O ly urging' the reservoir and gasket against the axle. 1 In testimony whereof l affix my signature.
